The Relationship field includes new settings allowing users to create and edit post on-the-fly from the post edit screen.

Field Settings

Iframe Arguments

The iframe which handle the post creation and edit will use URL parameters, allowing developers to use them.

https://www.domain.com/wp-admin/post-new.php?post_type=post&acfe_relation_type=add&acfe_relation_field_cid=acf129&acfe_relation_field_key=field_63c7834ac15e2&acfe_relation_field_name=post_object&acfe_relation_post_id=270&acfe_relation_is_admin=1

/**
 * acfe_relation_type=add                      // action type (add/edit)
 * acfe_relation_field_key=field_63c7834ac15e2 // field key
 * acfe_relation_field_name=relationship       // field type
 * acfe_relation_post_id=270                   // original post id
 * acfe_relation_is_admin=1                    // original request from admin
 */

It is possible to retrieve these arguments using $_GET or the acf_maybe_get_GET() function. Usage example:

add_filter('acf/prepare_field/name=my_field', 'my_prepare_field');
function my_prepare_field($field){
    
    // hide the field if inside the relationship iframe
    // originated from the front-end
    if(acf_maybe_get_GET('acfe_relation_is_admin') === '0'){
        return false;
    }

    // return normally
    return $field;

}
